冬小麦生长适宜光温指标研究
Study on suitable indexes of light and temperature for winter wheat growth
摘要
Abstract
According to the observational information of developmental phase of winter wheat of 45 agro meteorological observation stations in North China for the past 25 years, as well as daily meteorological data in the corresponding period, and by the method of standard normal distribution test, a partial of data that was skew distribution had been normalized, and then the paper designed possibility of less than 50% and 80% as the bound of optimum and comparative optimum indexes, so the suitable indexes for critical development stage of winter wheat was finally ascertained. According to the attribute of the breed, the indexes were divided into three types (springness, semi-winterness and winterness). The indexes contain suitable average temperature for every development phase and optimum accumulated temperature and sunlight of two adjacent development phases, so that the indexes could help winter wheat growth stage forecasting or meteorological conditions assessing. In comparison with the optimum indexes for each attribute type of winter wheat, the results showed that: the suitable temperature range of most development phases was raised with the winterness attribute enhanced , the average suitable temperature for the type of springness winter wheat was much lower than that of winterness and semi-winterness on the average, which was about 2 ℃ lower, however, compared with the semi-winterness type, the suitable accumulated temperature between the stage of tillering to overwintering and shooting was higher for the winterness type, and the suitable sunshine hours for winterness type of winter wheat was relatively high.关键词
